摘要
采用真型试验与数值模拟相结合的方法研究了输电线路防风偏问题。根据500 k V聊长Ⅱ线防风偏治理实际工程,运用有限元分析软件SAP 2000建立输电塔-线耦合体系的三维有限元模型。提出"边相阻挡、中相牵制"的柔性防范措施,开展输电线路风偏真型试验,并结合有限元数值模拟,研究柔性防范装置的动力响应特点,验证该装置的合理性及有效性。
The anti-windage yaw problem of transmission line was studied based on full-scale test and finite element simulation. According to a 500 kV Liaochang line 11 anti-windage yaw practical engineering, a three-dimensional finite element model of the transmission tower-line coupling system was established in SAP 2000. The flexible preventive measures of side phase barrier and middle phase hamper were presented. The full-scale windage yaw test of transmission line was carried out. Based on the finite element numerical simulation, the dynamic response characteristics of the flexible preventive device were studied, and the rationality and effectiveness of the device were verified.
